   Planning on getting the engine put back together next month and hopefully fitted. Need to run it in before the next stage begins.
   What head gasket thickness will I need to run. Saw this on eBay 380270491868. If not any other suggestions of where to get a good quality one from. It's running forged internals and low comp pistons if that helps.

   the stock gaskets are multi layer steel anyway, speak to your local main dealer.
   
   me and dean both use the 1.9mm genuine pug gaskets with no problem. we have run over 35 psi of boost on them!

   Sorry to but in, but whats the difference in gasket thickness? I assume its to do with the strength?

   gasket thickness is to do with one of two or both of below
   
   1)the compression ratio you want to run for mods your doing to the engine
   2)keeping the correct distance between valves and pistons after your head is skimmed to re-surface

    You'll want to work out the CR with different size gaskets, as if you are running low comp forged pistons then a very thick gasket might lower the CR too much and end up totally shit when off boost

    Might be a silly question. Block was boared to allow 79mm pistons. Will this affect the gasket I get or will I need to do soemthing to that aswell

    By boring out the block your CR is going to be slightly higher than standard bore
    
    Pistons then lower it
    
    But you don't know how much by, so you could just go with a 1.9 and probably be fine, but it's all guess work really
